+ You can use the
+ <a href="{@docRoot}reference/com/google/android/gms/wearable/ChannelApi.html"><code>ChannelApi</code></a>
+ class to transfer large data items, such as music and movie files, from a handheld to a wearable
+ device. The Channel API for data transfer has the following benefits:
+ <ul>
+ <li>Transfer large data files between two or more connected devices, without
+ the automatic synchronization provided when using
+ <a href="{@docRoot}reference/com/google/android/gms/wearable/Asset.html"><code>Asset</code></a>
+ objects attached to
+ <a href="{@docRoot}reference/com/google/android/gms/wearable/DataItem.html"><code>DataItem</code></a>
+ objects. The Channel API saves disk space unlike the
+ <a href="{@docRoot}reference/com/google/android/gms/wearable/DataApi.html"><code>DataApi</code></a>
+ class, which creates a copy of the assets on the local device before synchronizing with
+ connected devices.</li>
+ <li>Reliably send a file that is too large in size to send using the
+ <a href="{@docRoot}reference/com/google/android/gms/wearable/MessageApi.html"><code>MessageApi</code></a>
+ class.</li>
+ <li>Transfer streamed data, such as music pulled from a network server or voice
+ data from the microphone.</li>
+ </ul>
